Best Practices To Mitigate The Network Attacks

 Mitigation of Network Threats:

In this section we will discuss best practices we can use to mitigate various network threats. How do we better protect ourselves against various outsiders or even insiders that might be trying to compromise our network resources.
 
Signature Management:
we should use devices like an intrusion prevention system sensor or an intrusion detection system sensor, those sensors rely on signatures, patterns that allow them to recognize well known attacks. We should make sure to keep our signature database whether it's IDS or IPS or virus signatures, any sort of signatures that can help us identify malicious traffic.
Device Hardening:
we should not use the default configurations or default passwords. We should disable any unnecessary services that might be running on a device. If a server doesn't need to have web services running, maybe we disable web services on that server.

Change of Native VLAN:
Configure the trunk’s untagged VLAN to a non default value, to prevent unconfigured switch ports from automatically belonging to the native VLAN.

Defined the Privileged user accounts:
Define accounts for administrative users and add administrative privileges to those accounts rather than sharing a single ‘admin’ account.

File Integrity Monitoring:
There should be a method to monitor or detect any change in a critical system or files.

Role Separation/Least Privileges:
Assigns different sets of permissions to different categories of users, in an attempt to prevent conflicts of interest.

Honeypot:
Configure a host or network that does not have confidential information and keep this insecure to understand the techniques of the attacker to your organization.

Network Segmentation:
Logically subdivide the networks into different segments using VLAN or DMZ in an attempt to prevent specific users from accessing specific network resources.

Penetration Testing:
Perform authorized attacks to evaluate the level of security of the organization.

Analyzing Spear Phishing Email

Image
Phishing is the technique of fraudulent attempt by the attacker to obtain sensitive and confidential information i.e. Credentials, PII information, credit card, bank details. It can also be targeted attack to focus on the specific organization of individual. The attacker often tailors an email to speak directory to targeted user. There are many types of phishing as follow. I wouldn't explain the types. You can read Here . In this article you'll learn how to analyze the sophisticated phishing email. So, Let's start the case study to explain.  Spearphising :  Spearphising is the technique in which attacker aims at one person and lures him/her into providing confidential data. Attacker compile the email according to the specific user. The email would consist some of the target's email, username, designation.  Case Study: User receive the spearphising email containing the PDF attachment with double extension. Email body contains the unprofessional statement "Kindly m

Cyber Threat Intel

What is Cyber Threat Intel? Threat intel is the information about the threats. Cyber threat intel is used to better understand, predict and adopt to the behavior of malicious actors. It plays an important role in preventing the zero-day attacks. " Threat information that has been aggregated, transformed, analyzed, interpreted, or enriched to provide the necessary context for decision-making processes " (NIST). Threat Intel life Cycle: Intelligence lifecycle is the process of developing raw information into finished intelligence for policymaker to use in decision making and action. CTI Life Cycle Planning and Direction Planning and direction helps in setting up the goals for the threat intel program. Priorities and requirements are defined in this phase. Collection: Collection means gathering of data to produce the finished intelligence. Data includes logs(Firewall, IPS/IDS, Endpoints), threat feeds and OSINT(reports, social media, public forums). Collection Types of Collectio

Authentication Services

Image
  Authentication Services: In this section we will discuss the authentication services. The main goal of these services are to ensure that unencrypted credentials are not sent across the network. In other words they ensure that credentials are not sent in clear text. Kerberos: It is a network authentication mechanism mostly used in both windows active directory domain and some Unix environments. Kerberos provides mutual authentication that can help prevent MITM attacks and uses tickets to help prevent replay attacks. Working of Kerberos: The KDC(key distribution center) uses a complex process of issuing TGTs(Ticket granting tickets) and other tickets. The KDC packages user credentials within the ticket. Tickets provide authentication for users when they access resources such as files on the file server. These tickets are sometimes referred to as tokens. NTLM: New Technology LAN Manager is a suite of protocols that provide authentication, integrity, and confidentiality within windows sy
